kbdgen

A tool to build keyboard packages for a multitude of platforms using a single, simple text file definition. Supported outputs:

  • Linux (X11, m17n)
  • macOS
  • Windows
  • ChromeOS
  • iOS/iPadOS
  • Android
  • SVG
  • hit-error correction model as an FST, to be used with our spellers
  • CLDR keyboard definitions is presently missing, but is in the pipeline

We think it's pretty cool. Documentation (under construction -- how to update).

Runtime dependency

kbdgen uses convert which is part of imagemagick

For Mac: brew install imagemagick For Linux: <pkg-manager> install imagemagick

Installation

  1. get Rust
  2. clone this repo: git clone https://github.com/divvun/kbdgen.git
  3. cd kbdgen
  4. cargo install --path . (this installs kbdgen to the path)

Alternatively - download a precompiled binary from nightly builds:

Extract the archive, and move the binary to somewhere on your $PATH.

Example Usage

cargo run -- target --bundle-path C:\Projects\Divvun\keyboards\keyboard-sme\sme.kbdgen --output-path C:\KbdgenBuilds\sme_mac macos generate

Let's build an android app. There's two. divvun-dev-keyboard and divvun-keyboard. The former is the unstable one where we do all the testing. The latter one gets pushed to production. Both are deployed as separate apps in google playstore.

Alas, I digress.

We want to build divvun-dev-keyboard. Clone divvun-dev-keyboard.

cd source/divvun
git clone git@github.com:divvun/divvun-dev-keyboard.git
cd ../kbdgen
cargo run -- fetch -b /Users/srdkvr/source/divvun/divvun-dev-keyboard/divvun-dev.kbdgen #fetches deps
cargo run -- target --bundle-path /Users/srdkvr/source/divvun/divvun-dev-keyboard/divvun-dev.kbdgen --output-path ~/source/divvun/android_keyboard android build

Note - you will need imagemagick to run converting of images - so

$ brew install imagemagick@6
$ echo 'export PATH="/opt/homebrew/opt/imagemagick@6/bin:$PATH"' >> ~/.zshrc

Your typical commands are

  • ... android clone # Clones the base android repository
  • ... android generate # Generates all the layouts and speller configs, but doesn't clone stuff
  • ... android build # Both of the above.

TL;DR Android

Your

For Android run two commands:

kbdgen target --bundle-path C:\Projects\Divvun\keyboards\keyboard-sme\sme.kbdgen --output-path C:\KbdgenBuilds\sme_android android clone
kbdgen target --bundle-path C:\Projects\Divvun\keyboards\keyboard-sme\sme.kbdgen --output-path C:\KbdgenBuilds\sme_android android generate
